Profile of a public buyer

The most useful field in this route is the average number of bids received: it measures competitive intensity at that buyer. A buyer who systematically receives a single bid is not approached like one who receives eight.

What the route returns

Catalogue description, exactly as agents read it:

Procurement profile of a French public buyer (SIRET): contract counts and amounts, activity by year, top CPV segments, incumbent suppliers ranked with their contracts expiring within 18 months, framework-agreement share, average bids received per tender (competitive intensity) and median data-publication delay — the buying habits a bidder wants before a sourcing meeting. From DECP open data.

Expected identifier

The buyer's 14-digit establishment identifier.

A wrongly formatted identifier in the path returns 400 and is not billed — but it costs you a round trip. It is the leading cause of failed calls on the foreign routes. A search parameter, by contrast, is cleaned up: unsupported characters are stripped and the usable query is served.

Price and billing

Price: $0.02. The authoritative amount is the one in the 402 quote returned by the route itself — not this text, which derives from the same grid but is still just a page.

An error response cancels the payment: a 400, 404 or 503 is never billed. An upstream outage closes the route with a 503 rather than serving a degraded response.

How you pay

Every route is paid per call, in USDC or EURC on the Base network, over the x402 protocol: no account to create, no API key, no subscription. The first call returns a 402 quote your client settles, then replays the call. A failed call is never billed.

Would you rather have a euro invoice and prepaid credits? That is in preparation, and we will not announce a date until it is open. Write to contact@sirenic.eu and we will let you know when it opens.

Paid responses are Ed25519-signed: you can later prove what was served to you, and when. The whole catalogue is free to read in the OpenAPI document and in llms.txt.
